Too many SCIENTISTS are ill-informed of general science issues, phil of science, much less the wider logic, epistemology, ethics and metaphysics to make sound counsel. A SCIENTIST IN HIS LAB COAT SPEAKING BEYOND HIS SPECIFIC EXPERTISE IS NO BETTER THAN (AND OFTEN WORSE THAN) A COMMON-SENSICAL PERSON WITH A REASONABLE DEGREE OF PRUDENCE.

metaphysics? as in "what is the nature of reality"? That's the whole friggin point of science.

And a scientist in his lab coat speaking beyond his specific expertise is almost like a lawyer or a math/philosopher yamming on about biology.
